Patent JP-S63204522-A (JP)
Title: Laser recorder
Inventor: WATANABE HIDEO
IPC: G11B7/125
Filed: 1987-02-19
Abstract: PURPOSE:To fix the sharpness of a recorded image independently of image density by holding the gain of an APC circuit at an approximately constant value and approximately fixing the light emission responseness of a semiconductor laser independently of its optical output. CONSTITUTION:A V-P correcting table 14 for making the relation of a light emission level command signal S1'' to an optical output Pf linear is formed, and when the loop gain of an optical output securing circuit (APC) 8 can be secured at a large value, e.g. about 70dB, ideal relation can be obtained by the APC circuit 8, so that it is unnecessary to especially form the V-P correction table 14. When a beam scanning system for scanning an object an optical beam 4 is provided with an optical element such as a polarizing filter, an interference filter or an aperture restricting plate whose light emitting characteristics to the intensity of incident light is non-linear, the table 14 is formed so as to compensate also non-linearity. Consequently, the light emission responseness of the semiconductor laser can be held at an approximately constant value even if differential quantum efficiency is varied, the sharpness of the recorded image can be held at an almost constant value independently of the image density and continuous images with high picture quality can be recorded.

Title: Gas laser oscillator
Inventor: YOSHIDA MICHIO
IPC: H01S3/036
Filed: 1983-03-08
Abstract: PURPOSE:To equalize the density distribution of a laser gas, and to reduce output variation by providing a gas discharge section with a difusing and disturbing device generating the turbulence of the gas. CONSTITUTION:A dilute laser gas circulating in a vessel 15 by a blower 13 is fed to a gas discharge section (B) between a cathode 1 and an anode 3 and between a reflecting mirror 9 and another reflecting mirror. A revolution body 25 fills the role of a change into a turbulence of the flow of the laser gas fed to the discharge section (B). Consequently, the laser gas ionized by electron beams by glow discharge hardly collects to the cathode 1 side in the discharge section (B), and gas density is equalized. Accordingly, generated laser beams hardly vary with time.

IPC: C30B11/08
Filed: 1979-03-28
Abstract: PURPOSE: To obtain a single crystal of ferrite which has a uniform composition and is scores of centimeters long and to facilitate control for making the composition uniform, by improving the Bridgeman method for production.  
     CONSTITUTION: A heater 2 is fitted on the wall of an electric furnace 1 to set an appropriate temperature gradient in the longitudinal direction of the furnace. A core pipe 3 is inserted into the central part of the furnace 1. A crucible 5 is moved down in the core pipe 3 by a vertically moving unit 4. A material 6 for ferrite is filled in the lower part of the crucible 5. The crucible is slowly moved down by the vertically moving unit 4. As a result, the material 6 is completely molten. A crystal is then slowly grown upward from the bottom of the crucible 5. When the thickness of the liquid phase becomes an appropriate value, a solid of a composition for equilibrated coexistence with the liquid phase is supplemented into the crucible 5 and gradually molten with the growth of the crystal so that the thickness of the liquid phase is kept almost constant. This results in producing a large single crystal of uniform composition.

Title: Gas burner
Inventor: KAWAMURA FUTOSHI
IPC: F23D14/58
Filed: 1983-03-09
Abstract: PURPOSE:To enhance the stability and universality of flame by a structure wherein square wave-like irregularities are provided at the flame port surface side of a flame port plate. CONSTITUTION:Recesses 4a are provided at the flame port surface side of a flame port plate 4. Secondary air is supplied from the side of passage walls 1 and 1. During burning, complex vortices are developed at the flame port surface, because the flame port surface is not even due to the recesses 4a, resulting in improving the flame holding performance. In addition, the flame burning at the flame port near the recesses 4a heats the portion not dented with the recesses 4a or the convex parts, resulting in heating premixture at the flame port near the convex parts and at the same time supplying intermediate products developed in the burning near the recesses 4a. Thus, the stability and universality of flame can be enhanced by providing irregularities at the flame port surface side.

Title: System for converting graphics program
Inventor: SUZUKI KOKICHI
IPC: G06T11/80
Filed: 1989-02-17
Abstract: PURPOSE:To prevent change errors and the like when a change has occurred in a graphics program by constituting a system by means of a function identification means, an argument fetching means, an argument change means, a functional function dividing means and a function concerned calling means. CONSTITUTION:Since the argument change means 3 sets a fetched argument to be that which an argument selected in the function identification means 1 requests, the change is added to the argument which requires the change, the argument which becomes unnecessary is cancelled, and an appropriate value is added to the argument which the value lacks. Plural functions having equal functions, which are selected in the function identification means 1, exist in the functional function dividing means 4. When the functions to be used differ by the arguments fetched in the argument fetching means 2, the function is divided by the value of the argument and the function to be called is selected. The function concerned calling means 5 calls the function concerned which is selected by using the arguments which are added, deleted and changed by the procedure. Thus, only one correction work is needed even if the program is corrected and the change errors can be prevented.

CONSTITUTION:A model 1 of a one-side half machine is fixed at a specified attitude with a linear actuator 3. The model 1 of the one-side half machine is rolled and vibrated about a machine shaft 7 by air within wind tunnel to perform a flutter test. In this case, as the machine shaft 7 with which the model 1 of the one-side half machine is supported is positioned being separated at a sufficient distance l from a wall 10 of the wind tunnel on the side thereof, an air force distribution which becomes zero on the machine shaft 7 (pivot point) as a symmetrical plane of a machine body is obtained without being affected by the wall 10 of the air tunnel. In other words, an antisymmetrical air force can be obtained which approximates that in the case of a model of the whole machine.
